Question

The ratio of bit rate to Baud rate is 2. If bit energy is ${10}^{-6}$ J then the value of $d_{min}$ for M-Array PSK.

• A. 0.1
• B. 0.01
• C. $2\times {10}^{-3}$
• D. ${10}^{-3}$

Answer 1

The correct option is C $2\times {10}^{-3}$

$\frac{Bitrate}{Baudrate}=lo{g}_e.M=?\Rightarrow M=4$

$d_{min}=2\sqrt{E_s}.sin\frac{\pi }{M}=2\sqrt{2E_b}sin\frac{\pi }{4}[E_s=E_{b}lo{g}_{2}M]$


$=2\sqrt{E_b}$

$d_{min}=2\times {10}^{-3}$
